FLUSH TANK.

Application filed October 5, 1823. Serial No. 866,762.

To all whom it may concern:

Be it known that we, THEODORE CHARLES DOREDANT and HENRY PHILIP PFEFFER,citizens of the United States, residing at New Orleans, in the parish ofOrleans and State of Louisiana, have invented new and usefulImprovements in Flush Tanks, of which the following is a specification.

This invention relates to improvements in flush tanks, .the generalobject of the inven tion being to provide a siphon discharge for thetank with manually operated means for permitting the water level to riseto begin the siphon operation.

Another object of the invention is to so arrange the parts that thewater level is normally held at a point just below the point where itwill start the siphon action.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing our invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a sectional view through a tank supplied with our invention andshowing the parts in normal position.

Figure 2 is a similar View with the tank empty.

Figure 3 is a similar view with the parts in a position where the siphonaction is just beginning.

Figure 4, is a detail view of the actuating means.

Figure 5 is a sectional view taken on line 5-5 of Figure 4.

In these views 1 indicates the tank and 2 the discharge pipe which isprovided with a goose neck upper end for providing a siphon. The inletpipe is shown at 4 and the flow of water from this inlet pipe iscontrolled by a valve 5. An arm 6 is connected with the stem of thevalve and this arm is connected with one end of a channelshaped member7. A block 8 is pivotally arranged in the other end of the channelshapedmember and the rod 9 to which the float 10 is connected is attached tothis block. A bar 11 is pivoted in the channelshaped member and this barwhen in the member will engage the block and hold the same againsttilting movement. A handle 12 is connected to a ring 13 in the bar bythe links 14 so that when the handle is pushed down the bar will belifted so as to free the block 8 and thus permit the float 10 to riseupon the pressure of the water in the tank, and the channel-shapedmember 7 will drop under the action of gravity and the pressure of thewater against the valve and this downward movement of the channel-shapedmember will open the valve 5 so that more water will flow into the tankuntil the goose neck pipe 3 is covered and thus the siphon action willbegin so that the water is discharged from the tank. As the water leveldescends the float 10 will drop and thus pull the block from under thebar and thus cause the bar to drop back into the channel-shaped member.When the siphon action ceases, due to the uncovering of the ends of thesiphon pipe, the water will begin to rise in the tank until the partsare in the position shown in Figure 1 when the valve will close and nomore water will enter until the handle is again operated.

The handle 12 is substantially lighter in weight than the bar 11 and itsassociated parts, and therefore when the parts are in the position asshown in Figure 2 of the drawings, the weight of the handle will in noway effect the movement of the bar 11, but will move under the influenceof the weight of the parts as shown in Figures 2 and 3, while the normalposition of the handle and parts are shown in Figure 1.

From the above it will be seen that we have produced a flush tank whichrequires no discharge valve for holding the water in the tank as theonly valve used in the-device is the inlet valve.

It is thought fro-1n the foregoing tion that the advantages and novelfeatures of our invention will be readily apparent.

We desire it to be understood that we may make changes in theconstruction and in the combinationand arrangement of the several parts,provided that such changes fall within the scope of the appended claim.

What we claim is A flush tank comprising a siphon discharge pipe, aninlet pipe, a valve thereon,

descripa channel-shaped member connected With the valve stem, a blockpivotally arranged in the channelshaped member, a float having its rodconnected with said block, a bar pivoted in the channel-shaped memberand when therein preventing movement of the block a handle and means forconnecting the same With the bar to raise the same out of thechannel-shaped member to permit movement of the block by the float. 10

In testimony whereof We aflix our signatures.
